Debian squeezeApplication is C# on mono with a C .so underneath (timing is in the C library)It's just a port of triangle2 for now.1920x1080 HDMI outOther things running:SSHSambaLaunched from console - X is not running

It appears to all be down to the shader and the texture switches. With a simple shader and some mild overclocking (no overvolt) I get up to 62fps. With two full screen textures being drawn (with two draw calls) I only hit about 40fps.

one thing that can really drop the fps is to draw texture in blend mode (transparent on)if your texture does not really have alpha value that make some region transparent, disable the blend operation, this will allow for a higher fps when drawing on the entire screen but i beleive you are doing just some test anyway
